IGN had a chance to talk with actor Sam Rockwell while he was down in Austin promoting Jared Hess’ Gentleman Broncos at Fantastic Fest, and of course, they threw in a couple of questions about Rockwell’s upcoming role as weapons dealer Justin Hammer in next year’s anticipated Iron Man 2.

(Note: The title should be a hint that there is a plot spoiler in Rockwell’s response, so if you don’t want to know the answer, than stop reading here!)

They didn’t get anything too exciting out of the actor, but in talking about his character Justin Hammer, Rockwell did let slip that Hammer would be working with Mickey Rourke’s Whiplash to get revenge on Tony Stark. Rockwell told IGN the following:

“He’s a rival of Tony’s – they are competitors in the weapons industry. I team up with Michey Rourke and we decide we want to take him down and take down the Stark legacy. He’s sort of like a cousin of the Charlie’s Angels character I played. The smarmy cousin. But it’s Mickey – he does the fighting and the kicking ass in the film.”

When asked about playing the lead in a superhero movie, he told them he’d be willing to do one if he could do it with his Moon director Duncan Jones.

So what do you think? Makes sense that the very different Iron Man 2 villains team-up… just like in just about every superhero movie where there are two villains? And what about that idea of the guys behind Moon doing a superhero movie together?
